M2Tech Mitchell crossover: six programmable modules with adjustable frequency, slope and filter type
The Italian company M2Tech has unveiled the Mitchell analog active crossover. As stated, the novelty will be able to replace crossovers in two- and three-way speakers, getting rid of the disadvantages and compromises of passive circuitry.
In fact, Mitchell has six independent programmable analog modules. Each of them can “cut” its frequency range from the wideband input signal. In this case, you can select not only the values of frequencies from 50 Hz to 15,000 Hz, but also the slope of the decay or rise of the signal in the range from 6 to 30 dB / oct.
Each Mitchell crossover module is programmed to act as a low pass, high pass, or band pass filter. A notch filter or shelf function (gain band or cut band) is provided. Each module has independent adjustment of filters, output level and phase. There is also a choice of filter options: Butterworth, Chebishev or Bessel.
The crossover is configured from a computer connected to it via USB. For this, an application for Windows has been created, and its versions for Linux and Mac are promised soon. After setup, the device works independently.
The rear panel of Mitchell houses a full range of inputs and outputs, both unbalanced (RCA) and balanced (XLR). Mitchell has a trigger input to control the turn on. The app-programmable on-board IR receiver is ready to receive on / off commands from other M2Tech devices.
The cost of the Mitchell analog active crossover in Europe was 4,200 euro.
